How do I manage pain after lower eyelid fat repositioning surgery?

I am considering lower eyelid fat repositioning surgery, and I am wondering how long the post-operative pain will last. In particular, what is most important for care during the first few days? I would like to know the general level of swelling and pain, as well as the average time it takes to return to daily life. I would also appreciate any useful information or advice from those who have undergone the surgery. I need help!
